my biggest problem with the game was that it always tells you where to go, similar to fusion. And second the combat. first playthough i kinda liked it. it was cool fast and especially the sensemove made you feel like samus. Agile and acrobatic.
Second playthrough i was kinda "ey this game sort of reminds me of God of War and ninja gaiden and all those other button mashers."
The shooting in the Prime games are not a whole lot better though, but atleast there is something else besides shooting and general button mashyness.
I loved the Scan visor in Metroid Prime, scanning animals, plants, enemies and reading up on them.
Other M wasnt all bad, but it was far from great
